Determine requirements for exit scanner machine
We need to ask for a machine from TPA to run the new exit scanner, but going to write it I realise I don't know what the requirements are of that machine. We know that a t2.micro is too small but a t2.small is OK for the current network size. We should think though about planned network growth and if we should go for something we can grow in to instead of finding ourselves OOM and surprised at a bad time.
